Answer:
pH is an index of how many protons, or hydrogen ions (H+) are dissolved and free in a solution. The pH scale goes from 0 to 14. A fluid with a pH of 7 is neutral. Below 7, it is acidic; above 7, it is alkaline.
The more below or above 7 a solution is, the more acidic or alkaline it is. The scale is not linear—a drop from pH 8.2 to 8.1 indicates a 30 percent increase in acidity, or concentration of hydrogen ions; a drop from 8.1 to 7.9 indicates a 150 percent increase in acidity. Bottom line: Small-sounding changes in ocean pH are actually quite large and definitely in the direction of becoming less alkaline, which is the same as becoming more acidic.
If you think about it, we use descriptive words like this all the time. A person who stands 5’5” tall and weighs 300 pounds isn’t thin. If he loses 100 pounds, he still won’t be thin, but he will be thinner than he was before he went on the diet. (And we are more likely to comment that he’s looking trimmer than to say he’s not as fat as he used to be.)

Answer:
4.283M
Explanation:
Hi!
We are given a certain amount of CoCl2, and we are asked to make a smaller portion of it but with a stronger concentration. Dilution is a process where we use this equation: to find the unknown variable.
Think of it this way:
You put a powdered water flavor enhancer into your bottle. You put 5 drops of it, but it evenly distributes around the bottle so it tastes fine.
Now, you put it in a very small, miniscule cup. You have only a certain amount of water and 5 drops of water, but the flavor is so strong since there is less of the water. This is known as the concentration. Volume is just the water+flavor booster.
Let's convert everything to liters since the volume should be in units of liters.
250mL=0.250L
0.150mL=0.150L
Now, let's plug it in. The first two numbers go in the left side of the equation, and we do not know the concentration of the second so we will substitute a variable.
0.250(2.570)=x(0.150) <em>Isolate X.</em>
4.283=x
x=molarity of the solution
The second question asks how many mL of the first solution would you need....since the relationship of MV should be consistent, it should be all of the solution needed.
